I could not reproduce the main issue - i.e. create server from image; reboot, and on reboot server went to error state, I tested this in stable/2023.2 bobcat.
but as from observation if somehow server did created from volume instead of image (which is another bug), server can go to an error state as per this bug https://bugs.launchpad.net/nova/+bug/2048184
the bug is fixed in the master and is yet to be backported in Bobcat.
